ReDim Statement

Syntax:

variable: Any variable or array name.

typename: Keyword that declares the data type of a variable.

Byte: Byte variable (0-255)

Boolean: Boolean variable (True, False)

Currency: Currency variable (Currency with 4 Decimal places)

Date: 日付変数

Double: Double-precision floating-point variable (1,79769313486232 x 10E308 - 4,94065645841247 x 10E-324)

Integer: 整数変数 (-32768 から 32767)

Long: ロング整数変数 (-2,147,483,648 から 2,147,483,647)

Object: Object variable (Note: this variable can only subsequently be defined with Set!)

Single: 単精度型の浮動小数点変数 (3.402823 × 10E38 から 1.401298 × 10E-45)。

String: 最大 64,000 文字からなる文字列変数。

Variant: Variant variable type (contains all types, specified by definition). If a type name is not specified, variables are automatically defined as Variant Type, unless a statement from DefBool to DefVar is used.

object: Universal Network object (UNO) object or ClassModule object instance.

char: Special character that declares the data type of a variable.

In Collabora Office Basic, you do not need to declare variables explicitly. However, you need to declare arrays before you can use them. You can declare a variable with the Dim statement, using commas (,) to separate multiple declarations. To declare a variable type, enter a type-declaration character following the name or use a corresponding type keyword name.

array: Array declaration.

start, end: Numerical values or constants that define the number of elements (NumberElements=(end-start)+1) and the index range.

start and end can be numerical expressions if ReDim is applied at the procedure level.

Collabora Office Basicでは1次元および多次元配列を使用することができ、変数宣言をする際に変数型を指定します。配列は、プログラム中でリストやテーブルを操作する場合に適しています。配列を使用するメリットとして、インデックスを指定することで配列中の各要素にアクセスできる点がありますが、これらのインデックス指定には数値表式や変数が使えます。

Arrays are declared with the Dim statement. There are multiple ways to define the index range:

  Dim text(20) As String ' 21 elements numbered from 0 to 20
  Dim value(5 to 25) As Integer ' 21 values numbered from 5 to 25
  Dim amount(-15 to 5) As Currency ' 21 amounts (including 0), numbered from -15 to 5
  REM Two-dimensional data field
  Dim table$(20,2) ' 63 items; from 0 to 20 level 1, from 0 to 20 level 2 and from 0 to 20 level 3.

You can declare an array types as dynamic if a ReDim statement defines the number of dimensions in the subroutine or the function that contains the array. Generally, you can only define an array dimension once, and you cannot modify it. Within a subroutine, you can declare an array with ReDim. You can only define dimensions with numeric expressions. This ensures that the fields are only as large as necessary.
